British body-finding expert sent to help Madeleine detectives

Britain's leading body-finding expert has been helping in the hunt for Madeleine McCann.

The specialist police officer - who has not been named - is part of a team who have been deployed in Portugal to advise police in the hunt for the missing four-year-old.

He and his officers specialise in identifying sites where a body may have been hidden, based on information about suspects.

They are believed to have been part of a wider British police team helping with the case.

British sniffer dogs have also joined the search and are said to have found the "scent of death" in a car hired by Madeleine's parents.

The body expert, who has been in Portugal, has now returned to Britain.

He has been called in by London detectives investigating the disappearances of Xiao Mei Guo, 29, a Chinese DVD seller who was last seen at Whitechapel station in August, and Bonnie Barrett, 24, a single mother from Canning Town who vanished from Whitechapel's red light district in September. Police fear both women were murdered.
